Happy Pi Day: Vi Hart Challenges What We Know about Pi

(Repost from 03/14/2011)

Happy Pi Day!

What is Pi Day?
I’m a math educator and I’ve celebrated Pi Day for many, many years. It isn’t the most widely celebrated holiday, so let me explain what it means. Today is March 13, which can also be noted as 3/14. The mathematical notation Pi is rounded to 3.14, so math classrooms around the world celebrate Pi Day today.

Do We Have It All Wrong?
Vi Hart shared this video which challenges what we think we know and understand about Pi.

 

Paper Airplane World Record

Former Cal quarterback Joe Ayoob sets world distance record for throwing a paper airplane. I saw this during SportsCenter and I instantly started thinking about all the learning and fun that could be generated with this video clip. The STEM teacher in me just loves this sort of thing.

 

Educational Connections

Use friendly competition as a motivational strategy and challenge teams of learners to design the paper airplane that will travel the greatest distance. We are seeing greater emphasis placed on design and engineering in STEM areas on a number of fronts (Common Core Standards, recent grant RFPs, etc.). This would be a way to provide students with practical experience with design, project management, and more.

Consider cranking the discovery learning up a notch by providing non-traditional materials available, too. Will an airplane made of an entire sheet of newspaper travel a greater distance? Does the addition of paperclips to a plane’s design impact results?

Think way outside the box and challenge teams to work together using only non-verbal communication. This can really spice things up and promote creativity and higher-order thinking. My students always enjoy this and usually astound me with their creative communication strategies.

Let’s not overlook some of the more traditional connections. This can be an organic way to provide students with practice with measurement using both standard and non-standards units. This could be coupled with data collection, data anlaysis and the presentation of results through graphs and tables.

Those are just a few connections. Please share your ideas in the comments.

Visualization of Honshu Tsunami

“The Honshu tsunami was generated by a Mw 8.9 earthquake (38.322°N, 142.369°E ), at 05:46 UTC, 130 km (80 miles) E of Sendai, Honshu, Japan (according to the USGS). In approximately 25 minutes, the tsunami was first recorded at DART® buoy 21418. Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data.” (Source)

Much more information about this tsunami is available by the NOAA Center for Tsunami Research.

Bill Nye Headlines 2011 Martin Institute Summer Conference

The Martin Institute for Teaching Excellence is excited to announce that Bill Nye will be the keynote speaker for the 2011 Summer Conference.

About Bill Nye
Making science entertaining and accessible is something Bill has been doing most of his life. “My family is funny,” he says, “I mean funny in the sense that we make people laugh, not just funny looking.” Bill discovered that he had a talent for tutoring in high school, and while growing up in Washington, DC. He spent afternoons and summers de-mystifying math for his fellow students. When he wasn’t hitting the books, Bill was hitting the road on his bicycle. He spent hours taking it apart to “see how it worked.” <Read More>

Featured Speakers
Other featured speakers at the Summer Conference include Tom Barrett (a.k.a. @tombarrett), 21st century educator from Nottingham, England; Vaija Wagle, Harvard University Project Zero Group Leader; Carol Vukelich, distinguished educator in early literacy; and Tiffany Boyd, literacy coach and consultant with Heinemann Publishing.

Registration
Registration details for the Summer Conference are forthcoming. Sign-up to receive an email notification once registration begins. The 2011 Summer Conference will be held on Wednesday, June 15 and Thursday June 16, 2011, in Memphis, TN, USA.

Overview

“The acronym STEM stands for science, technology, engineering, and mathematics. The STEM fileds are those academic and professional disciplines that fall under the umbrella areas represented by the acronym. According to both the United States National Research Council and the National Science Foundation, the fields are collectively considered core technological underpinnings of an advanced society. In many forums (including political/governmental and academic) the strength of the STEM workforce is viewed as an indicator of a nation’s ability to sustain itself.”

1 Thing Teachers Should Know about Teaching with Technology

GUEST BLOGGER
Scott Rodgers

Part of the ongoing 1 Thing series.

When teachers start teaching with technology (and I do mean really teaching with technology), the first thing they better do is to “strap up their seatbelts and pull it tight”, because they are getting ready to go on the ride of their lives. Teaching with technology is a ride. You will find yourself trudging up the hill at times thinking you will never get to the top, yet at other times you will be flying down the hill wondering when you are ever going to reach the bottom.

buckleupApproximately 14 years ago, I along with several other science and math teachers from area schools took part in a 1 year workshop that met for 4 weeks over 2 summers and then once per month or so during school talking exclusively about technology in the classroom. The workshop entitled “Tech Tools” provided a launching pad for my use of technology in my Physical Science and Physics classroom. It especially introduced me to the use of Vernier technologies in the classroom. Upon completion of the workshop, I returned to school determined to figure out a way to put Vernier probeware to use in my classroom. With the help of the greatest technology director in the world, I received a $100,000 grant to buy probeware, computers, calculators, etc. Our science department went from having nothing to having what I firmly believed the best science lab in the area. I thought I was the technology guru!!! Not hardly. I did become a self-taught expert with Vernier equipment, but that is only where my ride began.

My students were exposed to excellent lab situations. I set up many of my labs as inquiry labs before Inquiry-Based Learning became “the thing.” I thought so anyway. The labs were always set up so as to have a “guide to the right answer.” I have since come to realize that true inquiry will result in a lot of wrong answers and that students learn as much from wrong answers as they do from right answers. With End of Course tests, I always argued that we just do not have time for wrong answers. Although it is a somewhat valid argument, I have done a much better job of letting my students get wrong answers as long as they are learning from them.

For my entire teaching career, if my students weren’t in the middle of a lab, they were in their seats and I was at my overhead projector. I loved lecturing and actually still do. I would walk around the room occasionally, but for the most part I could be found at the front of the room with my students staring at me as we went through a lesson. Last year to aid in classroom management, I along with the other physical science teachers bought a wireless mouse for our laptops, created PowerPoint lessons for every lesson we had and became “walk around the classroom lecturers.” Because our PowerPoints were self-made and pretty funny at times, our students enjoyed them, but still found themselves in their seats in a very static classroom.

Summer 2008 came along and after all those years of thinking I was a technology guru, I was treated to a week of Impact Training (named so because of a large technology grant our school system received). I finally got to tighten my seatbelt as I was about to spend a week with a group of educators who knew more about technology that I could ever imagine. We learned about podcasting. We learned about PowerPoint games (test reviews will never be the same again). We learned about Qwizdom (handheld response systems which can be used in conjunction with PowerPoints or used with their own software). We learned about Webquests (what a remarkable idea, students using the internet for learning while in the classroom). We learned that there was more than one type of multimedia presentation students could use to present research: Glogster, MovieMaker, and Audacity just to name a few. At first glance, it may seem like teaching would be easier when you are not standing up front at all times, but this semester has probably been one of the hardest of my career.

This semester has also been one of the most rewarding. My students are having fun. They enjoy class more than ever. There are still times they find themselves in their seats listening to me talk, but it will never again be a 1 ½ hour lecture. We break up lessons with Qwizdoms. We stop and look at different situations on the Internet. We work on multimedia presentations. We work on Gizmos from Explorelearning.com. As a teacher, you will not find yourself at your desk. You will be all over the place helping students, pointing students in the right direction, getting them back on task, etc. What a pleasure when you see a student finally ”get” a concept on their own and want to share that knowledge with the person sitting next to them.

Probably one of the greatest challenges, but also one of the most gratifying challenges is the ability to collaborate with other disciplines within the school. I spent 3 weeks working with an Advanced Functioning and Modeling math class studying roller coasters. It was an extremely tough 3 weeks, but quite possibly the most worthwhile 3 weeks of my entire teaching career. Our classes learned every possible physics concept as they applied to roller coasters on their own and applied those concepts as they built their own roller coaster with Legos. The students were able to Model data they gathered as a part of the math curriculum. I would never have dreamed this big 6 months ago. Before it was all said and done, our classes had completed a Roller Coaster Webquest designed by the math teacher and myself, they had gathered data using Vernier LabQuests, they modeled the data graphically, they built roller coasters they designed on their own with very little parameters, they created videos of their design/build and posted them to the school website and learned a lot about team work and thinking on their own along the way. What I discovered during this 3 week lesson was that using real technologies in the classroom takes much more work up front. I would hate to guess the number of hours put in prepping this lesson, but as I discovered it was time well spent. The lesson is still on my computer. I am ready to tweak the lesson and use it again next semester.

Teaching with technology is hard. It is hard on the teacher for all the reasons people throw out there for not wanting to do it. It doesn’t always work as planned. There will be times your lesson will not work at all. The Internet will go down at times. The students will try and check their personal email during class time. With only 2 years to go before retirement, why should I learn something brand new? I will tell you why, because our students deserve it!!! 21st Century Skills require the use of technology for a reason. It is not the way of the future; it is the way of the present. Using technology in the correct manner will add to your teaching and will also improve your students learning!!!!

So strap up and get ready for the ride of your teaching career, regardless of how far along you already are on your particular ride.

Your Class Can Interact with Astronauts

NASA astronaut Mark Polansky, who will be commanding the next mission to the International Space Station, has just posted a video to NASA’s official YouTube channel inviting YouTubers and Twitter fans to take part in his next mission, submitting video questions via YouTube and following mission updates over Twitter.

To ask a question, Polansky says to create a video of around thirty seconds and post it to YouTube, then send it to his Twitter account using an @reply. He’ll respond to the questions on NASA TV, which is broadcast nation-wide. (Source)

I encourage you and your students to participate in this activity. It’s a rare opportunity. Who knows? You may have a future NASA astronaut, controller or engineer sitting in your class!
